24. UDN Cacheable content :worldwide network of servers deploy at multiple points of presence.Cacheable content is pushed out to the edge of the Internet, close to the user/ Dynamic content: load balance across multiple origin sites,providing uninterrupted delivery of dynamic content and transactions

25. GTM GTM will intelligently load balance between multiple origin sites. If the site has failed, GTM combined with CDN allows continued delivery the site ’ s content. By monitoring network latency, link outages, packet loss, server memory and CPU utilization,determine the best server to serve the requests
